Mana Battery Raises $10.2M Seed Led by Voyager Ventures for Anode-Free Sodium-Ion Cells

Mana Battery Closes $10.2M Seed Round

Mana Battery, a Broomfield, Colorado-based battery technology company, has raised a $10.2 million seed round. Voyager Ventures led the round, with participation from Union Square Ventures and Buff Gold Ventures. The funding was announced on October 8, 2026.

What the Company Does

Mana Battery develops high-energy, anode-free sodium-ion cells built on a proprietary electrolyte platform. The company was spun out of the University of Colorado Boulder in 2023.

Its cells are assembled without an anode active material. Instead, the design pairs a self-extinguishing electrolyte with abundant, domestically sourced materials, an approach the company says cuts cost and supply-chain risk relative to lithium-ion.

Target Markets

Mana Battery's technology is aimed at several application areas:

• Defense
• Aerospace
• Rail
• Datacenter backup power
• Industrial UPS

The company is also co-developing cells with Saft under a 2026 joint development agreement.

Deal Context

The round is a seed-stage financing, reflecting early-stage investor interest in alternative battery chemistries that reduce reliance on lithium and imported materials. The participation of Voyager Ventures as lead, alongside Union Square Ventures and Buff Gold Ventures, gives the company a mix of climate-technology and general venture backers.

For acquisition-oriented observers, the combination of a proprietary electrolyte platform, anode-free cell architecture, and an existing co-development relationship with an established battery manufacturer (Saft) are notable structural elements to track as the company moves from seed stage toward commercialization.
